The Lowdown
Alright, folks, Rusty here. Let’s take a look at what Jaconé’s got lined up for us over the next couple of weeks.
We’re kicking off with a slow start. The swell is small—around 2ft to 3ft—and the wind is a bit all over the place. The water’s sitting at 72°, which is about what you’d expect for this time of year, so nothing unusual there.
The first real bright spot is on Wednesday, 30 July morning. The swell is a clean 3ft from the SSW, with a period of 11 seconds, and the wind is glassy. That’s a big win for clean conditions. The wave energy is moderate (175), so it’s not going to be a monster, but it’ll be fun and easy for intermediates.
Things start to look up a bit more as we head into Saturday, 01 August morning. The swell is 3ft from the S with a 12-second period, and the wave energy is moderate (403). The wind is offshore from the NE, so you’re looking at clean, peeling waves. Crowds can be around sometimes, but with conditions like this, it’s worth the company.
The real standout, though, is the long-range promise. Circle Monday, 10 August morning on your calendar. We’ve got a solid 4ft groundswell from the SSW, with a very long period of 13 seconds. The wave energy is strong (1068), and the wind is glassy. This is the kind of session that sticks with you—clean, powerful, and for experienced surfers only. The long period means the waves will have plenty of shape and punch, but it might close out a bit on the beach, so keep an eye on the setup.
Then, just a couple of days later on Wednesday, 12 August morning, it gets even bigger. We’re talking 7ft from the SSW, with a 12-second period and strong offshore wind from the ENE. The wave energy is very strong (2311). This is big, clean, and powerful—definitely for experts only. If you’ve got the skills, this is the session to aim for.
Overall, there’s a bit of a wait for the good stuff, but once we hit the second week, the quality jumps up. The first few days are small and a bit ordinary, but don’t write it off. The end of the run is looking like it could be something special.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
